由于数据是跨越 RAID 配置进行分段的(正如在 RAID 0 配置中一样),因此可以迅速存取数据。此外,由于有奇偶校验数据,因此在只有单个驱动器出现故障时,可以使用其它驱动器上的 奇偶校验数据重建该驱动器。三个 120 GB RAID 级别 5 驱动器的可用存储空间为 240 GB(用于存储数据),因为有相当于一个驱动器的空间留作奇偶校验数据之用。至少需要三个驱动器才 能创建 RAID 级别 5 配置。

配 置计算机以使用 R A I D

如果您在购买计算机时未选择 RAID 配置,则有时可能需要配置计算机以使用 RAID。您的计算机中必须至少安装两个硬盘驱动器才能设置 RAID 配置。有关如何安装硬盘驱动器的说明,请参 阅驱动器

要配置 RAID 硬盘驱动器卷,请先使用 Intel RAID Option ROM 公用程序,然 后再将操作系统安装到硬盘驱动器。必须先将您的计算机设置为启用 RAID 的模式,然后才能开始执行本说明文 件中的 RAID 配置步骤。

将计算 机设置为 启用 RAID 的模式

注 :只有订购的计算机具有 RAID 配置的情况下才能执行此过程。

1.进入系统设置程序(请参阅系统设置程序)。

2.按上箭头键和下箭头键以高亮度显示“Drives”(驱 动器 ),并按 <Enter> 键。

3.按上箭头键和下箭头键以高亮度显示“SATA Operation”(SATA 操 作 ),并按 <Enter> 键。

4.根据您的首选项,按左箭头键和右箭头键以高亮度显示“RAID Autodetect/AHCI”(RAID 自动 检 测/AHCI) 或“RAID Autodetect/ATA”(RAID 自动 检 测/ATA);按

<Enter> 键,然后按 <Esc> 键。

有关 RAID 选项的详细信息,请参阅系统设置程序选项

5.按左箭头键和右箭头键以高亮度显示“Save/Exit”( 保 存/退 出 ),并按 <Enter> 键退出系统设置程序并恢复引导过程。

使用 Intel Matrix Storage Manager(Intel 矩阵存储管理器)配置计算机以使用 RAID

注 :只有订购的计算机具有 RAID 配置的情况下才能执行此过程。

如果您已经有一个硬盘驱动器而且其上安装了操作系统,要添加第二个硬盘驱动器并将两个驱动器重新配置到 RAID 卷中,而不丢失现有的操作系统和任何数据,您需要使用适用于 RAID 级 别 0 配置(请参阅迁移至 RAID 级别 0 配置)、RAID 级别 1 配置(请参阅迁移至 RAID 级别 1 配置)或 RAID 级别 5 配置(请参阅迁移至 RAID 级别 5 配置)的迁移选项。仅在以下情 况下创建新卷:

要将两个新驱动器添加至现有的单驱动器计算机中(并且操作系统位于此单驱动器上),并要将两个新驱动器配置为一个 RAID 卷。

您的双硬盘驱动器计算机已被配置为一个卷,但卷上仍有一些剩余空间,您要将其指定为第二个 RAID 卷。

创建 RAID 级 别 0 配置

注 意 :执行此操作时,RAID 驱动器上的所有数据都将丢失。

注 :只有订购的计算机具有 RAID 配置的情况下才能执行此过程。

1.将计算机设置为启用 RAID 模式(请参阅将计算机设置为启用 RAID 模式)。

2.单击“Start”(开始 ),指向“Programs”( 程 序 )“Intel(R) Matrix Storage Manager”(Intel(R) 矩阵存储管 理 器 )“Intel Matrix Storage
